High quality Rotary Electric Actuator with Ball Valve Butterfly Valve Gate Valve for Environmental Protection
High Quality Rotary Electric Actuator with Ball Valve, Butterfly Valve, and Gate Valve for Environmental Protection
Application:
The PTK/PTM series electric actuators are designed for continuous multi-turn operations. They can be directly connected to various types of valves such as gate valves, globe valves, ball valves, and butterfly valves. The maximum output torque reaches up to 3500 Nm, making them ideal for industrial applications requiring high performance and reliability.
Advantages:
The PT/PTJ series actuators offer a wide range of mechanical and protective features that ensure durability and safety in harsh environments. Key advantages include:
1. Compact design with advanced manufacturing technology and top-grade imported components.
2. Non-intrusive design allows for debugging and parameter setting without opening the electric box cover.
3. Double-seal and double-protection structure ensures full waterproof and dustproof protection (IP68 rating, 3 meters for 48 hours).
4. Explosion-proof grade up to Ex d IIC T6 for safe operation in hazardous areas.
5. Flexible terminal connection options: plug connection or sunflower disk form.
6. Durable cast aluminum housing with powder coating suitable for extreme conditions. Optional coatings available.
7. Long-life worm gear set made from hardened alloy steel and bronze, fully supported by bearings.
8. Removable high-strength bronze stem nut for easy machining to match valve stems.
9. Manual override lever enables manual operation; automatically disengages when motor is powered on.
10. Multiple mounting options compatible with different valves and stems.
11. Three-layer paint system for corrosion resistance in severe environments.
12. Maintenance-free lubricant suitable for high and low temperature ranges.
Protection Features of PT/PTJ Series:
1. Torque protection
2. Valve limit protection
3. Auto-phase protection and correction
4. Instantaneous reversal protection
5. Phase loss protection
6. Motor start-up time-out protection
7. Motor thermal protection
8. Electrical protection with optoelectronic isolation (withstands 2000V surge voltage)
9. Automatic jammed valve discharge function
10. Power-down data protection
